NAME

       SDL_crc32 - Calculate a CRC-32 value.

HEADER FILE

       Defined in SDL3/SDL_stdinc.h

SYNOPSIS

       #include "SDL3/SDL.h"

       Uint32 SDL_crc32(Uint32 crc, const void *data, size_t len);

DESCRIPTION

       https://en.wikipedia.org/wiki/Cyclic_redundancy_check

       This  function  can  be called multiple times, to stream data to be checksummed in blocks. Each call must
       provide the previous CRC-32 return value to be updated with the  next  block.  The  first  call  to  this
       function for a set of blocks should pass in a zero CRC value.

FUNCTION PARAMETERS

       crc    the current checksum for this data set, or 0 for a new data set.

       data   a new block of data to add to the checksum.

       len    the size, in bytes, of the new block of data.

RETURN VALUE

       ( Uint32 ) Returns a CRC-32 checksum value of all blocks in the data set.

THREAD SAFETY

       It is safe to call this function from any thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
